A foot retention device ( 20, 100 ) includes a rigid vertical strut ( 40 ) and a springy band ( 30 ) disposed adjacent to an exterior side of the strut ( 40 ) and configured to flex over the strut ( 40 ) to form a non-drooping asymmetric arc that conforms to the profile of a human foot. A releasable securing mechanism ( 50 ) allows the band ( 30 ) to be easily secured and released. The foot retention device ( 20, 100 ) provides a fixed right angle (A) between a base plate ( 12, 180 ) and the vertical strut ( 40 ) allowing the user's foot to be inserted straight in. The foot retention device ( 20, 100 ) includes a non-sloping design for athletic applications, and a sloping design for footwear ( 200 ). Methods of assembling and manufacturing the foot retention device ( 20, 100 ) are also provided.
